Subject: [PATCH AUTOSEL 6.1 15/39] net: ipv4: fix return value check in esp_remove_trailer
Date: Sun, 29 Oct 2023 18:56:47 -0400 [thread overview]
Message-ID: <20231029225740.790936-15-sashal@kernel.org> (raw)
In-Reply-To: <20231029225740.790936-1-sashal@kernel.org>
From: Ma Ke <make_ruc2021@163.com>
[ Upstream commit 513f61e2193350c7a345da98559b80f61aec4fa6 ]
In esp_remove_trailer(), to avoid an unexpected result returned by
pskb_trim, we should check the return value of pskb_trim().
